POPI Complaint Voice Loggers

One of the key features of Next Four’s Managed Voice Services is its POPI complaint voice recording. But what does that mean exactly?

The “Protection of Personal Information Act” (POPIA) aims to ensure that any individual’s personal information remains protected and cannot be unlawfully collected, stored, and used.

In the business world today, we are confronted with an overload of information, so it becomes especially difficult to regulate the information your business collects to ensure POPI compliance. Fortunately, we can relieve some of that stress, by providing a completely POPI complaint voice recording solution.
